Screening of the literatures included in the Note Express 3.2.0. Assessment of the risk of bias in trials using Cochrane collaboration tools, and used Rev Man 5.3 to evaluate the curative effect. Results: 25 RCT, all in Chinese, there were 2257 cases. Of the 1216 cases who were treated, control group was 1041 cases. A random effect model was used for Meta analysis. The results showed that the effective rate of the treatment group was significantly higher than that of the control group, Differences were statistically significant (P=0.94, I2=0%), RR=2.87, CI [2.25,95 per cent 3.67], P<0.00001. Conclusion: There are limited evidence that LQFY is safe and effective in treating acne. However, this conclusion needs to be confirmed by a more large-scale, multi-center, high-quality RCTs.
